Two prominent lobate thrust fault scarps on Mercury, Discovery Rupes and Beagles Rupes, imaged by Mercury Dual Imaging System (MDIS) on the MESSENGER spacecraft. Discovery Rupes (left), named for the ship HMS Discovery, shown here in a MDIS high-incidence angle image mosaic, was first imaged by Mariner 10 in the mid-1970’s. Beagle Rupes (right), a bow-shaped fault scarp, was initial imaged during MESSENGER’s first flyby. Both fault scarps are cliff-like landforms that are over 1 km above the surround terrain.
